' FRUIT-JAR.

SPECIFICATION forming part of Letters Patent No. 512,349, dated January9, 1894.

Application filed April 6, 1893.

To all whom it may concern:

Be it known that I, ELEGTA WILLIAMS, a citizen of the United States,residing at Pavilion, (Vicksburg P. 0.,) county of Kalamazoo, State ofMichigan, have invented a new and useful Fruit-Jar, of which thefollowing is a specification.

This invention relates to that class of fruit jars, the covers of whichare attached to the jars by clamping or otherwise, in lieu of threadingthe jars and covering and screwing them together.

The object of the invention is to effect a greater utility andconvenience, by means of the construction described and claimed below.

In the drawings forming a part-of this specification, Figure 1 is aperspective view, with parts in vertical section; and Fig. 2 is aperspective view of a lettered detail from Fig. 1.

Referring to the lettered parts of the drawings, A is the jar, the topof which is flanged outward all the way around, as at B. Formed in thetop of this flange is a circular groove, into which groove is placedarubber packing ring, 0. The cover, D, is provided with a circular rib,E, on the under side, which rib-rests on the packing ring 0, and whenthe cover is clamped down the jar is completely sealed and the packingring thoroughly protected and held by its groove from displacement. Thiscover, D, has a circular groove, F, formed in the upper side, over therib E.

In Fig. 2 is shown a spider, G,'formed with a series of radial legs,having downwardly extending ends, H, which ends are placed in thegroove, F, Fig. 1, and is employed to bear down upon the cover.

Serial No. 469|Z72- (No model.)

on to the upper end of the threaded stem, J, is an internally threadedthumb-nut, L, Fig. l. The parts are shown in Fig. 1. ready to clamp thecover down on the jar, which is done by screwing the thumb-nut, L, downfirmly on to the spider G, as indicated by the dotted position of thethumb-nut in said figure; which action of course bears down on the .allair from the interior of the jar, which might remain in the jar but forthis downwardly extending portion.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent ot the United States, is

The combination of a jar outwardly flanged at the upper end, said flangebeing provided ,with a groove in its upper surface, a packingring insaid groove, acover provided with the circular rib fitting on to saidpacking-ring, said cover having a circular groove in the upper side, aspider having a series of arms, the ends of which are adapted to fitinto said groove, a jaw adapted to pass on to the cover and the flangeof the jar and to catch under said flange, said jaw being provided withan upwardly extending threaded stem, which stem passes loosely throughsaid spider, and a thumb-nut on the end of the stem; substantially asset forth.

In testimony to the foregoing I have hereunto subscribed my name in thepresence of two witnesses.
